      1. Install Mongo from the 10gen apt repository.
      2. Run mongod in a shell, perhaps with different configuration, port bindings, etc.
      3. Run "/sbin/start mongodb"

      Expected behaviour:

      • starts MongoDB and outputs something like mongodb start/running, process 12345

      Actual behaviour:

      • refuses to start MongoDB due to second running instance, and prints mongodb stop/waiting

    Description

      The upstart configuration installed by the mongodb-10gen package from http://downloads-distro.mongodb.org/repo/ubuntu-upstart uses start-stop-daemon(8) to control the spawn of /usr/bin/mongod. It currently doesn't use a pidfile to track the lifecycle of the process, and thus falls back to the default behaviour of scanning the process table for an extant instance of a mongod process.

      This means that when, for example, mongod is running inside an LXC container on the host, the upstart script will fail to start MongoDB.
